What species are high in Omega 3

Almost all fish, including shellfish and crustaceans, contain levels of Omega 3 fatty acids. The table below from the 2007 Handbook Australian Edible Oils highlights 25 species with high levels of Omega 3 fatty acids. Variations on the amounts do occur between species due to their diets. Higher pelagic species such as swordfish and tuna will have higher levels of Omega 3 fatty acids.
Most aquaculture fish contain Omega 3 fatty acids. The levels will be dependent on the feeds used to grow the fish. Atlantic Salmon, for example has a high level of Omega 3 fatty acids whereas a Silver Perch (fresh water) has a lower level.
